Summary: This study reveals the role of Kupffer cells (KCs) in monocrotaline (MCT)-induced liver injury. By depleting KCs and administering anti-TNF-alpha antibody, researchers found that KCs depletion can reduce liver injury and lower TNF-alpha levels. Further investigation revealed that KCs can induce hepatocyte necrosis by activating the RIPK3/MLKL pathway. Additionally, ER stress and NF-kappa B pathways were also found to be involved in KCs activation.

Summary: This study aimed to investigate the role of TNF-alpha and its receptors in regulating Kupffer cell polarization and downstream inflammation pathways during TCE sensitization, in order to clarify the mechanism of TCE-mediated immune liver injury. The results showed that TCE sensitization led to exacerbated liver injury, activation and polarization of M1 type Kupffer cells, increased expression of TNF-alpha and its receptors, and upregulation of downstream inflammatory factors. Inhibition of TNF-alpha/TNER1 pathway with R7050 reduced M1 Kupffer cell polarization, downstream signaling pathway activation, and inflammatory factor secretion, alleviating liver damage.

Summary: TLR7 plays a critical role in ConA-induced liver injury, and its deficiency attenuates liver damage and reduces the release of hepatic pro-inflammatory cytokines. TLR7 deficiency also inhibits the proliferation of CD4+ T cells stimulated by ConA and specifically suppresses the expression of TNF-alpha in liver Kupffer cells. Depletion of Kupffer cells abolishes the detrimental role of TLR7 in ConA-induced liver injury.

Summary: The delivery of disease-relevant antigens by polymeric nanoparticles has shown to induce immune tolerance in various disorders. This study investigated the contribution of liver sinusoidal endothelial cells and Kupffer cells in nanoparticle-induced tolerance in a mouse model of multiple sclerosis. The results suggest that both cell types play important roles in the induction of tolerance through the secretion of specific factors and interaction with CD4 T cells. This mechanistic support provides insights for the development of biomaterial platforms in clinical trials.

Summary: This study demonstrated the important role of STING signaling in septic liver injury, with significant effects on liver function protection and attenuation of systemic inflammatory response. In addition, STING signaling activation resulted in LPS-induced liver injury through promoting hepatocyte death. Release of mitochondrial DNA (mtDNA) was identified as one of the mechanisms for STING signaling activation.

Summary: This study investigates the mechanism of liver injury induced by the environmental poison imidacloprid (IMI). The results show that IMI induces pyroptosis in liver Kupffer cells and this effect is suppressed by P2X7 inhibition. Animal experiments also demonstrate that both P2X7 inhibitor and pyroptosis inhibitor can reduce cell injury level.

Summary: Liver transplantation is a effective treatment for end-stage liver disease and significantly prolongs the survival time of patients, but acute and chronic rejection still remain major obstacles. Investigating induced immune tolerance is of crucial theoretical significance and socio-economic value. This paper comprehensively summarizes the important roles of Kupffer cells in establishing immune tolerance after transplantation, including phagocytosis, cell polarization, antigen presentation, and cell membrane proteins, providing a theoretical basis for further study and clinical application of Kupffer cells in liver transplantation.

Summary: This study identified an immune-cloaking mechanism induced by radiation therapy (RT) and revealed the crucial role of the cGAS-STING pathway in this process. RT increased the expression of PD-L1 in liver cancer cells, inhibiting the activity of T cells and protecting tumor cells from immune clearance. The study also found that RT enhanced the antitumor effect of PD-L1 axis blockade and increased immune cell infiltration.

Summary: This study investigates the role of the gut microbiome in regulating response to radiotherapy in hepatocellular carcinoma (HCC) patients. The study found that dysbiosis of the gut microbiome impairs the antitumor immune response and leads to variations in the effectiveness of radiotherapy. The cGAS-STING-IFN-I pathway was identified as a key mechanism in this process. The study proposes cyclic-di-AMP as a potential target for modulating response to radiotherapy in HCC patients.

Summary: This study validates the upregulation of PD-L1 in tumor tissues after radiotherapy (RT) and demonstrates that higher post-RT serum sPD-L1 is associated with poor prognosis in hepatocellular carcinoma (HCC) patients. Additionally, patients with higher rate of sPD-L1 increase after RT show better treatment response and longer survival.
